False. Each atom of calcium needs two atoms of fluorine to create an ionic compound. The atom of calcium could gain stability if it gives the last two electrons in the highest energy level. The fluorine atom only can accept one electron in its highest level of energy to complete it and to reach the lowest energy level. This is the reason because an atom of calcium needs two atoms of fluorine.

Which describes the molecule shown below?
lana [24]

Answer:

Option D. Saturated alkane

Explanation:

To know which option is correct, it is important that we know what saturated and unsaturated compounds are in this context.

Saturated hydrocarbons are compounds which has only carbon to carbon single bonds (C–C) in its chain. A very good example of such compound is the Alkanes.

Unsaturated hydrocarbons are compounds which has either a carbon to carbon double bond (C=C) or a carbon to carbon triple bond (C≡C) in its chain. Examples of such compounds include alkenes and alkynes.

Now, let us answer the question given above bearing the meaning of saturated and unsaturated compounds in mind.

The compound given above contains only carbon to carbon (C–C) single bond.

Therefore, the compound is a saturated alkane.
